Well what about this one this last afternoon, a guy in a Malibu departs from Tipton VFR asking for IFR clearance, is told to turn immediately back to land (Violating the ADIZ), and crashes (from the redboard string).

Let there be no doubt.
He was oblivious to VFR ADIZ procedures, obviously didn't even take the internet course, or if he did didn't understand it, and if he was already in IMC he was super dangerous. And let's not go saying it's the ADIZ's or ATCs fault. They didn't reach out and stall the aircraft.
